Abstract (en)
[origin: US6012907A] A flow-regulating arrangement for a hydraulic transport device such as a vane-cell pump includes partial-transport flow throttles which operate independently of one another and which are arranged in parallel to deliver output of the hydraulic transporting device to a hydraulic load. One of the partial transport flow throttles responds to the pressure difference between working pressure of the hydraulic transporting device and pressure within a pressure chamber internal to the device.
